MiP ProMini Pack - 16MHz/5V

MiP with ProMini Pack on its back

Attribution

This project is based on the now retired Sparkfun MiP ProMini-Pack.
The original Eagle files can be found on GitHub. They were created by Sparkfun employee Casey Kuhns.

Project Goals

  • Produce a functional version of the MiP ProMini-Pack to correct the MiP communication issue in the Sparkfun original.
  • Run the ATMEGA328 at 16MHz instead of 8MHz. This allows the AVR to properly receive 115200 bps serial output from the MiP.
  • Increase Vcc from 3.3V to 5V so that the ATMEGA328 can reliably run at 16MHz.
  • Modify board layout to make it easier to hand solder the SMD parts.
    • Use larger 0805 passives instead of 0603.
    • Extend the pads on some of the SMD packages to allow for easier transfer of heat from the soldering iron.
  • Port my MiP C API project to Arduino and refactor it to make it more closely resemble other Arduino libraries.
